基于TCMGIS的槲蕨的生态产地适宜性分析

目的：应用《中药材产地适宜性分析地理信息系统》（TCMGIS）分析槲蕨Drynaria roosii Nakaike产地适宜性，为槲蕨的科学区划及种植提供依据。方法：以槲蕨代表性的分布地区为分析基点，选取年平均气温、海拔、土壤、降水量、日照、相对湿度等影响槲蕨生长发育的关键生态因子，通过野外调查设置生态因子的数值范围进行分析。结果：表明槲蕨适宜产地分布在我国的亚热带季风地区，集中在云贵高原一带，即贵州大部、云南东部、广西西部和湖北西部、湖南的边界地区。在广东、福建、四川、浙江等地也有零星分布。讨论：研究成果可为合理规划槲蕨种植生产布局，开展引种栽培工作提供科学依据。

TCMAE based Adaptability Evaluation for Drynaria roosii Nakaike

We analyzed the appropriate growing area for Drynaria roosii Nakaike using a geographic information based TCM adaptability evaluation system (TCMAE). In the study, TCMAE was used to analyze the desirable growing area for D. roosii based on the optimized ecological factors, including averaged annual temperature, altitude, soil type, precipitation, sunlight, and relative humidity. Weight value of each key factor was also evaluated based on the data collected in the field survey. Analysis result showed that the potential areas desirable for growing D. roosii sit in the subtropical monsoon region in the country, mostly on the Yunnan-Guizhou Plateau, covering the most part of Guizhou, the east part of Yunnan, the west part of Guangxi, the west of Hubei, and border areas of Hunan, though Guangdong, Fujian, Sichuan, and Zhejiang have limited areas desirable for growing the herb. It is important to sort out the appropriate growing area for D. roosii through TCMAE. The system provides scientific evidences for transplanting and cultivation of D. roosii in China.
